CONVEYER.

To all whom it may concern:

Be it known that we, HENRY B. SAUER- MAN and JOHN A. SAUERMAN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Conveyors, of which the following is a specification.

()ur invention relates, more especially to conveyers for transferring material, such as coal, crushed stone, gravel, sand or other material, from a pile thereof along a hori- Zontal, or substantially horizontal plane, and thence to the place of dumping; and our primary object is to provide a simple con struction of conveyer which will be adequate to perform in a highly satisfactory manner the work to be accomplished.

Referring to the accompanying drawing, Figure 1 is a view in side elevation of a portion of conveyer apparatus constructed in accordance with our invention, showing the bucket or scoop in the position it assumes as it travels along the material to be scooped preparatory to scooping up a portion thereof; Fig. 2 is a view like that of Fig. 1, showing the bucket in the position it assumes after it has been operated to fill it; Fig. 3 is a view in sectional elevation of the apparatus illustrated in Fig. 1 with the parts in the position therein illustrated; Fig. at is a view similar to that of Fig. 3 showing the parts in the position illustrated in Fig. 2; and Fig. 5, a section taken at the line 5 on Fig. t and viewed in the direction of the arrow.

The conveyer-frame is represented at 6 and in the construction shown comprises four upper and lower parallel channel-bars 7 and 8, respectively, forming guide-tracks arranged with their channels 9 and 10 opening toward each other as represented in Fig. 5, and braces 11 connecting the bars together. The channels 10 afford opposed guideways in which travels a conveyer-chain 12 of an endless type comprising links 13 pivotally connected by pins 14 each of which carries a roller 15 at its opposite end, the roller being confined in the guideways 10 to permit the chain to be guided in its movements. Resting in the guideways in the upper bars 7 are rollers 17 in which a shaft 18 1s journaled for supporting a depending tripping device in the form of a bail comprising two arms 19 preferably weighted toward their lower ends, and a connecting rod 20. The

Specification of Letters Patent.

shaft 18 is connected to a cable 18 intermediate its ends, the cable extending around a sheave (not shown) at the end of the conveyer frame to bring the two free ends of the cable 18 together so that they may be manipulated together to position the trip device at any point along the conveyerframe.

The bucket or scoop 21 is attached to the conveyer-chain 12 at a point of pivotal connection of one link thereof with another, through the medium of arms 22 journaled at their lower ends to the outer faces of the scoop-sides 23 and 24, as indicated at 25 and 26, and at their upper ends one shaft 27 which takes the place of the usual link-connecting pin at that point.

The bucket employed is preferably of ordinary scoop shape with each side 23 and 2% having straight converging edgeportions 2S and 29 and a rounded portion 30 between which sides the inclosing wall 31, for joining the sides together, extends. The wall 31 thus presents a rounded portion 32 and two converging straight portions 33 and 34, one of which is cut away as represented in the drawings to afiord an opening 35 and a penetrating edge 36 for engaging with the material to be scooped in a manner hereinafter explained. The lower ends of the arms 22 are pivoted to the sides 23 and 24 located be tween the converging portions 23 and 29 so that the arms are preferably pivoted to one side of the center of gravity and extend from such position to the other side of the center of gravity at which they connect with the conveyer-chain, the bucket thus tending to tilt downward at its rounded port-ion.

The normal position of the scoop, and the position it assumes while traveling over the material to be scooped, is that illustrated in Figs. 1 and 3 in which it rests at its mouth or open portion in substantial contact with the material. Studs 37 are provided on opposed sides of the scoop to engage with the upper edges of the arms 22, and thus arrest the tipping of the bucket at its rounded portion; and hook-shaped lugs 38 located 011 the rounded portion of the wall 31 preferably extend in the positions illustrated in the drawing for engagement with the trip device, as hereinafter described.

In the operation of the conveyer the chain 12, driven by any suitable power device, (not shown) is caused to drag the bucket in the direction indicated by the arrow in Fig.

1, and cause it to engage at its rounded endportion with the trip-device, thereby swinging the latter and causing it to engage at its bar 20 with the lugs 38, whereupon continued movement of the chain causes the bucket to be turned on the arms 22 to the position illustrated in Figs. 2 and t, thus inverting it. Turning of the bucket, as described, causes its penetrating edge 36 to be forced into the material on which the bucket is traveling and describe an are through it, thereby causing material to be scooped up, whereupon the bucket in its inverted and filled condition may be moved to the desired point of discharge by further movement of the chain, and there (lumped in any desirable manner.

The trip device is automatically released from engagement with the lugs 38 by the turning of the scoop as described, and when this disengagement has been effected the trip device swings to its normal depending position for again engaging with the bucket when the latter is again caused to be brought into engagement with the trip device.

It is manifest that if desired a plurality of buckets 21 may be connected with the conveyer-chain 12, as by dulication thereof, and thus as the buckets successively engage the trip-device they will be caused to scoop up material as described of the bucket 21.

While we have illustrated and described our invention as embodied in the form of conveyor which moves in a horizontal path, we do not wish to be understood as limiting our invention to its use in so-called horizontal conveyers, as it may be embodied in a .conveyer operating in an inclined direction, or one in which the bucket engages a pile of material having a substantially flat or inclined upper surface, and after filling is raised to the point of dumping, a type of conveyer operating in this last referred-to manner being that known as the vertical yp iVhat we claim as new and desire to secure by Letters Patent, is
